|Long Term Support Strategies for Open Architecture COTS Assemblies||November 2009||Programs are increasingly turning to COTS assemblies in order to gain timely access to the latest technology under favourable commercial terms. There is a potential downside though in that by design COTS building blocks utilize commercially available components, the availability of which is governed by wider market forces. As a result, in order to guarantee supply, it is vital that any COTS procurement is supported by a Long Term Support strategy appropriate to the program. In part this strategy has to mitigate, or even eliminate, the effects of obsolescence but it also has to address all factors required to support maintenance, repair and upgrades to fielded equipment. This paper will explore a range of techniques that when added together as part of a coherent strategy can provide Long Term Support tailored to program timescale and financial needs.|

|Technical Needs and Challenges in Harbor Surveillance||May 2009||High frequency sonar applications are not a new concept. Navies of the world have been using high frequency sonar to seek out mines for the past sixty years. More recently however, a growing imperative to counter terrorist threats to harbors and coastal areas has created the need for a new range of high frequency sonar products, designed to detect and track specific surface and underwater targets such as divers, swimmers and water vehicles. As a consequence, COTS vendors of acquisition products have been forced to re-examine, and in some cases redesign, existing technical solutions to cope with the very demanding requirements of these applications. Click on the attached white paper to read the newest approaches to acquire and process high frequency sonar signals and the benefits over older traditional approaches.|
|Advances in Radar Processing||February 2009||With radar systems, as with many other military applications, it is difficult to determine whether the requirement for greater processing capability has driven the development of more powerful hardware and software – or whether radar systems designers have been quick to perceive the opportunities presented by more capable hardware and easier-to-use software.

|High-Speed Data Acquisition for Medical Imaging Utilizing SDR Technology||December 2008||New medical technologies often hold great promise, but few patients will benefit unless an effective implementation can be brought to market at a reasonable cost. One of the most cost effective ways of developing new solutions is to leverage techniques and equipment developed for other purposes. Medical ultrasound, which borrows heavily from naval sonar, is probably the best known example, but other technology developed for military purposes is also being adapted to medical uses. With the introduction of Abaco Systems ICS-1650, developers of PC-based medical imaging systems now have a native PCI Express slot card that provides high performance signal acquisition capability with leading edge FPGA based DSP resources, at a very reasonable price.|
|DSP Libraries and Graphical Tools Accelerate Distributed Corner Turn Development||March 2008||Virtually every radar application requires many FFTs on a set of radar pulse returns. The FFTs are normally performed in fast time dimension (row data) or in the slow time dimension (column data). However, mathematical operations performed on column data are normally very slow as column data is not contiguous in memory. This means that streaming accesses are not available, and SDRAM pages may need to be opened and closed; it is therefore faster to perform a matrix transpose or “corner turn” on the column data then process the slow time dimension FFTs on rows of data. This matrix transpose operation is extremely straightforward if the FFT processing is performed with a single embedded processor. However, real-time constraints usually mandate the use of multi-computers where the data flow and processing are much more complicated. This white paper will show how DSP libraries and graphical tools accelerate this distributed corner turn development.|
|AXIS - Taking the Sting out of Multiprocessor DSP Application Development||February 2008||These days a Systems Engineer faces a number of issues when configuring and programming a complex, heterogeneous multiprocessor system for a Mil & Aero application.

How to move data around the system across widely different interconnects? How to map the application onto the system and how to see the application’s performance in real-time? How to re-scale the application to a different sized system without a major rewrite and how to migrate the application to new processors and interconnects?

|Real Time Ethernet||January 2006||To many readers, the idea that Ethernet could ever be used for real-time applications is a contradiction in terms. Ethernet is famously unreliable because it does not establish a unique, dedicated connection between one sender and one receiver. Unless a dedicated connection can be introduced into this chaos, Ethernet has no role in real-time networking. This paper describes an innovative way to overcome this inherent limitation of Ethernet.|
